Filed: 1985-07-24
Abstract: PURPOSE:To prevent a wave-shaped erased state caused by a zigzag array, and to execute a good erasion by providing a light transmitting dust-proof cover which has formed a light shielding slit in its line direction, on light emitting elements of each line which is arrayed zigzag, by positioning it in the vicinity of their optical axis. CONSTITUTION:Light shielding slits 4a, 4b of two lines are formed in the line direction on a light transmitting dust-proof cover in accordance with a zigzag array of an LED being light emitting element. In case an LED1 which represents an odd one ius turned on, light which is regulated by the slit 4a and transmits directly through the light transmitting dust-proof cover 3 is generated, and also light which travels to an LED2 side for representing an even one is reflected by the side of the slit 4b and transmits through the light transmitting dust-proof cover 3 along the optical axis. In case the LED2 is turned on, as well, it is relatively the same as case, and a light quantity distribution goes to distribution having a light emitting center in the vicinity of the center axis phi. Accordingly, an erased state of a wave shape corresponding to a zigzag array can be eliminated.

Title: Method and device for transmitting data corresponding to picture element in video image through telephone line
Inventor: ROORENSU DEI IMONZU
IPC: H04N7/00
Filed: 1989-06-28
Abstract: PURPOSE: To make the amount of video data to be transmitted maximum and to prevent the occurrence of large errors in a received video by specifying data allocation on I and Q channels, transmitting a synchronizing signal when the transmission of data packets starts and initializing a demodulator for the phase of the synchronizing signal. CONSTITUTION: At the time of transmitting data by the in-phase(I) channel and a quadratic phase(Q) channel by using quadrature amplitude modulation(QAM), the adjacent amplitude of a sine wave cycle in the data packet in the I channel and the Q channel is allocated to adjacent chromaticity value, gray value or luminance value and it is allocated to the picture element whose overlapped sine wave cycle in the I channel and the Q channel is the same or to the adjacent picture element. Then, the synchronizing signal is transmitted when the transmission of the packets starts. The synchronizing signal simultaneously executes the two functions for showing the start of the new packet and the function for initializing a demodulator phase detection circuit by using the phase. Thus, the error of a detection signal can be reduced.

Abstract: PURPOSE:To produce the optical waveguide by using a flame deposition method in such a manner that the thickness of a glass film and dopant distribution are nearly uniformalized by moving a burner approximately at a specified speed and depositing glass particulates while setting the rotating speed of a turn table at a high speed when the burner comes to the inner side of the revolving shaft of the turn table and at a low speed when the burner comes to the outer side thereof. CONSTITUTION:A glass particulate layer 120 for a lower clad layer is first deposited and the deposition thereof is executed in the same manner as for the deposition of another glass particulate layer 130. A substrate 10 is arranged on the turn table and the turn table is rotated. The turn table is simultaneously moved back and forth in its radial direction in such a manner that the glass particulates generated by the burner fall onto the entire surface of the substrate 10, by which the glass particulates 120 are deposited on the substrate 10. The glass particulates are heated together with the substrate 10 at a high temp., by which the glass particulates are vitrified to transparent glass and a glass film is formed. The burner is moved at approximately the specified speed and the glass particulates 120 are deposited on the substrate while the rotating speed of the turn table is set at the high speed when the burner comes to the inner side of the revolving shaft of the turn table and at the low speed when the burner comes to the outer side thereof.

Feedback voltage Vf is brought to a negative value and an output from the integrator 14 is minimized at the same time. When the output from the integrator 14 reaches a lower limit value Va, the output from the comparator 15 reaches positive voltage, the MOSFET 16 is turned OFF and field currents are increased while feedback voltage Vf reaches 0, and the output from the integrator 14 is augmented.

Title: Highly accurate vibration analyzing system
Inventor: HATAKE SUSUMU
IPC: G01H17/00
Filed: 1986-07-15
Abstract: PURPOSE:To accurately calculate not only a displacement but a vibrational stress in a frequency response analysis by adding a modified mode wherein the effect of an external force term is taken into consideration in addition to an intrinsic mode by mode superposition method. CONSTITUTION:A modified mode 2 wherein the effect of an external force term is taken into consideration is added in addition to an intrinsic mode 1. A missing portion is generated in the external force term in case of only the intrinsic mode 1. Since the portion missing from the external force term is removed by adding the modified mode 2 wherein the effect of the external force term is taken into consideration, a highly accurate calculated value can be obtained. Thus, not only a displacement but also a vibrational stress can be accurately calculated in a frequency response analysis.

Title: Photocuring method
Inventor: KAMATA HIROTOSHI
IPC: C09D4/00
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a method for photocuring a photocurable material by irradiation with near-infrared rays, wherein the feature of infrared curing can be exhibited without deactivating surface free radicals by supplying an aqueous solution of a water-soluble organic polymer to that surface of the material which comes into contact with air. SOLUTION: This method comprises applying an aqueous solution of a film- forming water-soluble polymer to that surface of aphotocurable material which comes into contact with water and irradiating the material with light in the visible to near-infrared region. This method can alleviate the problem that near-infrared rays generate few free radicals and the curing of the surface cannot be performed due to the deactivation of surface free radicals by oxygen though the rays can reach depths even when the material is one containing a pigment and a filler. The water-soluble organic polymer used is polyvinyl alcohol, polyethylene oxide, carboxymethyl cellulose, starch or the like. The photocurable material used is one containing an ethylenically unsaturated compound, a near-infrared to visible ray radical polymerization initiator, and a filler such as a pigment.
